In the year 2016, following a series of carefully planned out suicide attacks on numerous US cities by a new group of Muslim extremists who have dubbed themselves "Allah's Chosen Soldiers", or ACS for short, the US has developed contracts with several elite Private Security Companies in order to crush the ACS while it is still growing. The government has ordered the contractors to capture or kill several people suspected to be highly involved in the group's actions globally. The government has also supplied these companies with an unrestricted spending limit, allowing them to obtain the latest and greatest weaponry necessary to take down this new threat to America.
